Appendix B IR-IP Interface Module ASMi-52 Installation and Operation Manual
B-10 Performing Preliminary Configuration
Changing the LAN IP Address of a Configured IR-IP
The LAN IP address of an already-configured IR-IP can be changed while it
operates. This means it is not necessary to turn ASMi-52 off before starting the
configuration procedure. Note however that the IP traffic flow through IR-IP will
be disrupted until the other stations in the IP network learn the new address.
To change the LAN IP address of an already-configured IR-IP, use the procedure
described above for a new IR-IP with the following differences:
• Configure the destination address of the ping utility to the new LAN interface
IP address. It is not necessary to change the Telnet host source address.
• When ready, set section 1 of the IR-IP DIP switch to ON.
The ERR indicator starts flashing faster (approximately four times a second).
• Perform steps 4, 5 of the procedure used for a new IR-IP.
What to Do If ...

The LINK indicator (10BaseT version) does not light immediately after
ASMi-52 is turned on
The IR-IP interface module does not receive power from the ASMi-52 power
supply. Service is required.
After the power-up process ends, the LINK indicator shows LAN integrity. It may
stay turned off without indicating power supply failure.

The ERR indicator does not light immediately after ASMi-52 is turned on
IR-IP is faulty and must be replaced.

After turn-on, the ERR indicator lights for 15 seconds, and then turns off. ACT
lights from time to time, but there is no response from IR-IP
One of the following:
• No software loaded into IR-IP. Download software using the procedure
described in the Downloading New Software section below.
• IR-IP has been configured. If you do not know the current IP address of the
LAN interface, erase IR-IP router configuration using the procedure given in
the Erasing User’s Configuration section below.

No ping replies from IR-IP
If your host does not begin to receive ping replies after three unsuccessful
attempts, check the physical connection path between the Telnet host Ethernet
interface and the IR-IP 10BASE-T connector.

The IP learning process is not successful
Check that the prescribed IP address does not appear in the ARP table.
